5 Virtualization Value Server consolidation and infrastructure optimization Pools common infrastructure resources Breaks legacy one application to one server Physical infrastructure cost reduction Reduces hardware, real estate, power and cooling costs Improved operational flexibility and responsiveness Reduces time spent on provisioning, configuration, monitoring, and maintenance Increased application availability and improved business continuity Eliminates planned downtime Virtualization will be the most impactful trend in infrastructure and operations through Gartner *Source: Gartner, Virtualization Will Drive Major Change in IT Infrastructure and Operations in the Next Three Years, May 8,

6 New Backup Challenges Virtualization Changes Server, lication, and Information Paradigm Backup Must Evolve to Deliver Even Greater Consolidation and Value OLD PARADIGM Low overall server utilization and plenty of bandwidth for backup NEW PARADIGM High overall server utilization, but little bandwidth for backup 6

7 Introducing EMC Avamar Revolutionizes Backup with Global, Source Data De-duplication Reduces the size of backup data at the source before it is transferred across the network reducing backup times by up to 10 times Reduces required network bandwidth and the amount of data backed up daily by up to 500 times De-duplicates across sites and servers for maximum efficiency Cost-effectively stores a greater number of full backups on disk reducing or eliminating the need for tape Ideal for protecting remote offices, VMware environments, LAN servers in the data center enabling fast, reliable, and secure backups over existing network connections 7

8 Avamar: Optimized Backup for VMware Infrastructure Avamar De-duplicates at the Optimal Location and Level of Granularity Optimal location: Reduces data at the source Duplicate data never traverses congested shared resources Data backed up is reduced from ~200 percent to ~2 percent of primary weekly Significantly reduces contention for shared resources De-duplicates within and across virtual machines and/or VMDK (virtual machine disk format) files Optimal granularity: Sub-file, variable-length segments VMDK is one large file; any changes cause an incremental/full traditional backup Fixed-length segment de-duplication fails due to frame offset Sub-file, variable-length segment de-duplication finds changes anywhere in VMDK Dramatically cuts the amount of data backed up daily Significantly reduces daily backup time Ideal for the protection of VMware environments Enables fast, secure backups over existing virtual infrastructure Permits greater server consolidation and maximum value from VMware 8

9 How Source De-duplication Works Global Data De-duplication Instances Client agent scans the data for changes Modified files broken into sub-file variable length segments Only unique sub-file segments are backed up Queries local file cache to identify and disregard static files Compresses and applies a hash to each object Queries local hash cache, and then the Avamar server to determine if objects are unique Avamar Data Store or Avamar server 9

10 Avamar: How it Works Simple Example of Global, Source Data De-duplication First Instance Data Center Duplicate Instance Remote Site 1 Modified Instance Remote Site 2 Only unique data segments are backed up A B C D Data already backed up, so only unique IDs stored (20 byte pointers) E New data segment identified and backed up A B C D E De-duplication Server (stored backup data) 10

11 Target and Source De-duplication Only Source-Based De-duplication Reduces Network Bandwidth Requirements and Provides Immediate, One-Step Restore TARGET DE-DUPLICATION SOURCE-BASED DE-DUPLICATION B B B B B B Backup Server De-duplication Device Avamar Server Up to 50 times reduction in backup storage Moves ~200 percent of primary data weekly Backups are typically restored from full and incremental images Data viewed as file systems and/or virtual tape library target for traditional backup environments Up to 50 times reduction in backup storage Moves ~2 percent of primary data weekly Up to 500 times reduction in network impact Up to 10 times faster daily full backups All backups are full; immediate, single-step recovery Next-generation backup and recovery 11

27 Backing Up VMware Infrastructure Before Avamar Data center re-design focused on server consolidation and virtualization Concern about traditional, tape-based backup in VMware environment Backup windows strained; physical resources overburdened With Avamar Deployed agents within virtual machines 95 percent reduction in data moved 90 percent reduction in backup times Major reductions in NIC, CPU, and memory usage Centralized management and control Avamar provides a huge time and cost savings for backup of multiple virtual machines. With Avamar, we can centrally manage all of our backups, and we also gain the ability to rapidly restore data down to the file level.

28 Global Industrial Manufacturer Before Avamar Struggling to meet backup, recovery, and reliability goals Shipping tapes offsite risky, slow recovery With Avamar Backup for VMware (24 ESX Servers, 332 virtual clients) Avamar agents installed in VM guests Backup performance increased tenfold Backup network traffic reduced by 95 percent Reduced backup and recovery administrative burden Eliminated physical tape management 28

29 Fortune 20 Healthcare Supplier Before Avamar Growing VMware environment struggles to meet backup window Daily tape backup and offsite tape shipments risky, slow recovery Unable to quickly replicate data via WAN for disaster recovery With Avamar Global de-duplication effective within and across VMDK files Over 70 percent reduction in first backup and average of 99.7 percent thereafter Compared to traditional alternatives, testing showed Avamar moved one-fifth of the data that Symantec PureDisk moved Avamar moved 190 percent less data than traditional tape backup software moved 29
